Hello,
According to the information provided by POGA on its website, the monitor could be replaced:
"We have two options for exchanging the monitor:
1. You send us your POGA and we exchange it in Germany.
2. We send you a new monitor incl. mount and instructions on how to exchange it yourself.
Please note that you will be charged for a new monitor + shipping/taxes

Please send us an email at hello@poga.gg or contact us via WhatsApp at +49 151 62441442. We will assist you as quickly as possible."
